Definitions

  • This invention relates to an anti-theft device for cars, which does not require modification in the esthetics of the vehicle in which it is to be installed, and, which ensures an optimum degree of security.
  • the anti-theft device of the present invention is based on a completely different functional philosophy, specifically on the absence of elements that must be forced, i.e., there are no mechanical parts which offer resistance to the attempted theft.
  • the steering wheel when the device is in the anti-theft position, becomes uncoupled from the steering linkage, and can thus turn freely in either direction, without fulfilling its purpose as a drive transmitter. Consequently, the vehicle cannot be maneuvered.
  • the steering column is divided into two sections, with their ends grooved axially in the direction of their generatrices, and, the respective sections are coupled or uncoupled from each other by an internally grooved coupling bushing under the control of a key actuated mechanism.
  • the basic principle of the invention resides in cutting the steering column into two sections, and then using a device to couple or decouple the respective sections.
  • FIG. 1 is an exploded side elevational view of the various elements making up the anti-theft device of the invention, some of which appear in cross-section;
  • FIG. 2 shows the same elements in assembled relationship, also in partial cross-section
  • FIG. 3 shows the device in perspective
  • FIG. 4 is an exploded cross-sectional view of an alternative embodiment of the invention.
  • the anti-theft device comprises a coupling cylinder 1 and a drive cylinder 2, whose axes cross at an angle to each other, the angle depending on the type of car in which the device is to be installed.
  • the steering column extends through the coupling cylinder 1 and is divided into two sections.
  • the top section 3 is connected directly to the steering wheel, and, the bottom section 4 is connected to the steering linkage for the vehicle wheels.
  • the respective sections are separated from each other when the device is in the anti-theft position, and are coupled to each other by a sleeve 5 when the device is in the drive position.
  • the top section 3 of the steering column has a cylindrical stop 6 integral therewith, and, spaced from the stop 6 has a splined portion 7, which is spaced from the stop 6 by a cylindrical portion 8. Its free end terminates in a stub 9 which is received in a bore 10 in the bottom section 4, thus maintaining the two sections in axial alignment.
  • the bottom section 4 has an integral cylindrical stop 11, and a compression spring 12 mounted on it.
  • the end of the section 4 is provided with continuous splines.
  • the two sections 3 and 4 of the steering column are journalled within the coupling cylinder 1 in bearings 14 and 15, which hold the said sections of the column in alignment and in a fixed axial positions by their engagement with the cylindrical stops 6 and 11.
  • the longitudinal splines 7 and 13 on the respective sections of the steering column enable axial displacement of the coupling sleeve 5, which has corresponding internal splines 16 and 16'.
  • the internal splines 16 are spaced from the splines 16' by an unsplined portion of a length slightly greater than that of the splined portion 7 of the first section 3 of the steering column.
  • the external periphery of the coupling sleeve 5 is circumferentially grooved at 17 in order to provide a toothed rack profile extending axially of the sleeve 5 and overlying the internal splines 16.
  • the coupling cylinder 1 has an internally splined narrowing 1', which moves in an outer perimetral recess of the coupling sleeve 5, corresponding to its splines 16', as shown in FIG. 2.
  • This narrowing can be positioned at the opposite end of the coupling cylinder 1, as is illustrated in FIG. 4, in which the said narrowing is marked with reference number 1".
  • the coupling sleeve 5' lacks the said perimetral recess and is positioned with the coupling cylinder 1 through the opposite end thereof, as is also illustrated in FIG. 4.
  • the sleeve 5 When the sleeve 5 is in the bottom limit position as shown in FIG. 2, it is maintained stably in that position by gravity, with the splines 16 and 16' meshed with the spines 7 and 13, respectively, of the steering column sections 3 and 4. Hence the sleeve 5 provides a direct coupling between the steering linkage of the wheels and the steering wheel.
  • the splines 7 of the top section 3 are positioned within the smooth central portion of the sleeves between the splines 16 and 16', and the splines 16 are positioned over the cylindrical portion 8, whereby the said upper section 3 linked to the steering wheel can turn idly in either direction, without transmitting its movements to the bottom section 4 or to the steering linkage.
  • Axial movement of the sleeve 5 is controlled by drive mechanisms located within the cylinder 2, and which include a pinion 18 having teeth cut at an angle, which are meshed with the rack 17 on the coupling sleeve 5.
  • the axle of the pinion 18 extends to both sides of the pinion and includes two tongues 19 and 20.
  • the first tongue 19 links up with a group of contacts 21 of an electric switch controlling the engine.
  • the second tongue 20 couples to the locking elements, specifically to a cotter 22 of a cylindrical body 23 to whose head, through pins 25, the drum 26 of the lock is fixed.
  • a bushing 27 capable of shifting axially a short distance, as allowed by a stub 28 on being interlocked in the recess 29 of the drum 26. This displacement is performed against the compression of a spring 30, and the assembly is completed with the auxillary bushing 31 and the enclosing housing 32, through whose front the key 33 is inserted.
